Ok. Here are the idea so far (from this board and two others)
Use it for a flying saucer hoax which will cause mass panic about oncoming alien invasion (Several votes). Line it with little mirrors, tinfoil, ect to create either a large spotlight or a solar powered satellite dish cooker. Use it as a giant Guacamole dip dish. Build a parabolic reflector mic. Use it to build a 1920s style “Death Ray”. Enhance the hit-surface of the toilet bowl. Use it as a snow saucer, a protective cup or cover it with glass and turn it into a table. Put some holes around the bottom to use as a colander when making large amounts of spaghetti. Use it to surf on open wireless networks on the other side of town. Make a birdbath out of it (which was my very first thought). I could go as the Gladiator to my next Halloween party or just wear it as a large, silly hat -or a hat for rice patty farming. Build a swimming pool for midgets. Use it as body armour in a gunfight, a la, Senor Eastwood. The base of a fire bowl for summer evenings. Tie myself to a speedboat and use the dish instead of waterskis. -AKA “Waterdish’ing”. Snail racing Indy 500 style, grease 'em up and watch them crash.
sycorob had several ideas…
- Oversize Discus competition.
- Giant Frisbe ™
- Put a base on it, have a bunch of people over for the superbowl and serve chips and salsa out of it.
- Really big bowl of soup.
- Put a strap on it to turn it into a shield, arm yourself with a light saber, and head out to the nearest Ren Fair armed with futuristic technology. They’re bound to make you king.
- Build a model of the starship Enterprise, using the dish as the main hull.
- Sell on Ebay. Somebody will find a use for it.
I could mount a magnetron from an old microwave oven in front of it and cook food on the other side of town (AKA a 2020s-style “Death Ray”). Use it as a giant Wok. Bury it in my yard, convex side up, leaving the topmost portion of the round visible through the dirt. then put some stakes around it and rope it off, and put a sign beside it that says “DANGER! UNEXPLODED LAND MINE. STAY BACK 50 FEET.” Attach it to the top of my car. and get vanity plates that say “MTHRSHP” OR attach it ‘correctly’ to the top of my car and pretend I have satellite TV in my car.
Anything else?
NOTE: I will be using one or more of these ideas.
If you have a good throwing arm, send it spinning down the road, rocking and rolling and disrupting the neighborhood. Would work best on a long slope.
Any clues as to which of the ideas you are favoring?
I went the other way (DirecTV to Dish), so I also have a spare one.
How about the world’s biggest (or at least wierdest) cymbals?
Incidentally, DirecTV dishes and LNB’s (the things at the focal point of the dishes) will work with DishNetwork receivers, and vice-versa.
I’m not sure yet. I like the mirrored cooker/spotlight and birdbath ideas the best so far.
Althought I am tempted in the 1920’s (or 2020’s) style death ray. The guy down the street has been bugging me lately. I do have an old microwave around here somewhere 
Take it to the bank and pretend like you thought it was an old fifty cent piece and try to cash it in. But make sure you do it on a Friday. Pretend like you can just make out the “queen of america’s potrait” on the “heads” side.
Use it to get a $400 rebate.
Buy a DVB receiver and an LNB.

Candy Dish.
I think I like you, *TeaElle! 
See. I’m flustered…
You could always find the “Bloom County” strip that has the diagram for converting a home dish into a satellite transmission jammer.
Stick it on your head and walk around the supermarket talking into the protruding piece like its a hands free phone.
Paint it red, white and blue, and go Halloweening as Captain America this year!
- Take your dish off the house and then chase those darn kids off your grass
- ???
- PROFIT
Paint a message on it and aim it at the sky: “ISS - YOU NEVER CALL!”
Eyepatch.
